Reminder to self: see how widespread support for the TCP BBR congestion control algorithm is.

The TCP BBR congestion control algorithm was introduced in September 2016 and became available in Linux kernel 4.9 in July 2017 after being in the news for a good 5 months (see links below). It strives for better bandwidth use and lowering latency on big data pipes.

This post is a reminder myself to see how widespread that is on recent distributions for both end-user and server systems.
